To cZZ whom t may concern.'

Be it known that we, SAMUEL G. RHODES and ALBERT B. RYrINsKI, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful mprovemert in Electric Time-Switches, of which the following is a. specification.

The invention is an electric ltime switch, which acts automatically at any predeter# mined time in the twenty-four hour day' to set .in operation a translating deVice-such as an installation of glow-lamps-and at a later time toterminate said operation.

The invention consists more particularly in the construction whereby the movement of a switch member actuated by the time mechanism is arrested and then released I either to open or close circuit, as the case may be, to the translating device.

ln the accompanying drawings- Figure 1 is a. front, and Fig. 2 is a side elevation, of

three successive positions. Figflis a side circuit-breaker associated with the electro-v I. view of the same mechanism in the position of Fig. 3, the switch being then open. Fig. '7 is a. side view of the same mechanism in the Aposition of Fig. 6, the switch 'being then closed. Figs. 8 and 9 are detailed views showing in two positions the mercury magnetwhich actuates the pendulum. Fig. 10 is a section of the sleeve on shaft 23, which sleeve carries the switch arms 39, 40. Fig. 11 is a diagram showing the electrical circuits.

Similar numbers of reference indicate like parts.

'The motorelectromagnet 1 is adjustable on the threaded rod 2, projecting from the suppprting back-board 3. The curved plate .armature f1 of the magnet is'disposed below the same, and is 4carried by a bent arm 5, which is secured to a barb, of insulating material, which bar 6 is' suspended by leaf springs 7 from a bar 8 protruding from the back-board 8.

The bent arm 5, above its point of fastener ing to bar 6, is curved outwardly `to clear the bar 8, and at its upper end carries a awl 9 which engages. with a ratchet wheel A Q .'fasNear the lower bent over end of arm. 5

there is an opening to receive a clamping screw to secure the turned over extremity of the pendulum rod 11 on which is received the bob 12, movable up and down on said rod and adjustable thereon by means of the nut 13.

When the electro-magnet 1 is energized, it moves its armature 4, to the right, from the position shown in Fig. 8, to that shown in Fig. 9,- thus causing the pawl 9 to engage with a tooth of ratchet wheel 10 and turn said wheel. denergized, 'the backward swing of the pen- -dulllilm 'causeslzpawl 9 to 'run over the ratchet teet 1 net is accomplished b the fol owing means:

When the electro-magnet 1 is f Supported on the bar 6 is awire frame 14, x I

in which is placed a curvedA glass tube 15, containing mercury. A circuit termin'al 16 enters said tube at one end' for a. considerable distance. A circuit terminal/17 entere said tube near the other end. A branch wire a from the plus maimlead connects to terminal 16. Terminal 17 is connected by wire l; to one terminal of magnetA 1, the other terminal of said magnet being connected by branch wire c to fthe nega-tive main lead. When the pendulum bob hangs vertically as in Figs. 1, 2 and '11, the mercury is out of contact with terminal 17,l and the magnet is not energized. When the bob is swung to the left, as shown in Fig. 8, circuit is established at terminal 17, and when said bob is swung to the right bythe attraction of magnet 1 upon its armature 4, as in Fig. 9, 4circuit is broken at said terminal 17. The

ratchet wheel 10 operates the switch mecha-- "On t e outer end of shaft 28 is the dial 25,

marked' for the twenty-four hours of a day, and toothed around its circumference. The

hub 26, Fig. 2, of 'said dial receives and is secured to said shaft 23.. On said hub and between a shoulder 27 anda fixed plate 284 are pivoted' two cam plates 29, 30, each of which plates may be rotated on saidhub independentlyfottha 'athen twocam plates are alike, so that a description of one and its associated mechanism applies equally to the other.

Referring to Figs. 3, 5, 6, the cam plate 29 is integrally formed of metal and has two arms, one of which, 3l,l extends to the circumference of dial 25 and has a projection 32 which engages with notches on said circumference. The other arm carries at its end a cam 34. rfhe function of the cam 34 is to raise successively two spring latches or stops 35, 36, which are pivoted in lugs 37, Figs. 2 and 5, on the rear side of the front member of frame 24.

On the shaft 23 is a rotatble sleeve 38, Figs. 1, 4, and 7, of insulating material, which carries a plate, from which project two oppositely disposed switch levers 39, 40, which coperate with two contact clips 4l, 42, secured on said front member. These clips are disposed in different vertical planes, and the switch levers 39, 40 are similarly disposed. llVhen the shaft 23 is turned so that the levers 39, 40 do not register with the clips 41, 42, as shown in Figs. 3 and 4, then said levers do not close Contact between said clips. lVhen the levers .39, 40 do register withclips 4l, 42, as shown in Figs. 6 and 7, then said levers do close contact between saidclips. Surrounding shaft 23 and seated in a countersink in sleeve 38, is a helical spring 43, Fig. l0. One end of this spring is connected to shaft 23, and the other end.

to sleeve 38. Fast on the outer end of sleeve 38 is a plate 44, Fig. l0, carrying two arms 45, 46.

Considering now simply the sleeve 38, with its switch levers 39, 40, and radial arms 45, 46, it will be obvious that when the shaft 23 is rotated by the'motor mechanism described, the motion of said shaft will be transmitted through helical spring 43 to sleeve 38, unless said sleeve be prevented from rotating, in whiclncase the e'ect of rotation of shaft 23 will be to wind up spring 43. If afterward the sleeve 43 be released,

then the sleeve will be rapidly turned by the wound spring. until its motion is again mechanically arrested.

The function of the radial arms 45, 46 is to prevent rotation of the sleeve 38 until released. Consider the position of the parts shown in Fig. 3: rlhe helical spring 43 has rotated sleeve 38 until arm 46 has encountered pivoted stop 35, which arrests further movement of said arm, and hence further rotation of sleeve 38. Shaft 23, continuing to turn, winds up spring 43. 'The switch levers 40, 39 do not register with their clips 41, 42. The cam 34 is just moving into po s'ition tv o raise stop 35. As it does so, it frees arm 46 from said stop. The helical spring 43, now turning the sleeve 38, throws arm 46 forward to engage the next stop 36,

Fig. 5. The cam 34 continuing to move onincasso tion, as shown in Fig. 3, and circuit at the switch levers being again interrupted.

The actual setting and operation of the device is as follows: The lamp 48*, Fig. 1,1, merely represents translating apparatus or installation of any kind, to which it is desired to provide a supply'of current over a certain period of time in the twenty-four hour day. The device is first regulated as a time piece, by a. suitable adjustment of the pendulum bob 12 and by turning the dial (the set screw 48, Fig. 2, which connects its hub to shaft 23, being loosened for the purpose, until the scale indication which comes opposite the fixed index 49 (Fig. 1) corresponds to clock time. 'Thus in Fig. l, the number 5 on the dial opposite the tired index, the dial being so adjusted at the hour of 5 p. m., as shown by the standard clock. Circuit is Aopen at the switch levers 39, 40. lt is desired, for example, to close circuit to the lamp at 7 p. m. rFlic projection 32 on arm 3l of cam plate29 is in serted in the notch on the circumference of dial 25 which is opposite to the number 7. Just before the dial has rotated sufficiently to the right of Fig. 1, to bring the number 7 in front of the i'iXed index 49, theA cam 34 on arm 33 of cam plate 2S) first raises the stop 35 and then the stop 36. rlhe switch levers 39, 40 being now freed (and, as already described, at the instant of 7 oclock) are swung around into the position shown in 6 and 11, to close circuit to the lamp 48:11 We have thus determined the moment when the current supply will be started. vWe have now to fix` the instant of cutting oft' that supply. -All that is required is`to set the cam plate 30 so that its projection 50, Fig. 3, will enter tlresiotch on the dial periphery, indicatinghef desired time of stoppage. Thus in Fig. l, said projection 50 engages with the notehnpposite the hour mark 6 a. m. nthe manner already described, and just before the hour mark 6 a. m. comes opposite the iixedgindex `49, the cam 47 will release the two stops 35, 36, as before, and the switch levers will be rotated to interleo rupt circuit. As here shown, the device may be set to establish current supply at any time during the twenty-four hour day, and to continue for any given length of time within that period; but, of course, the dial can be marked for any desired time units and in tervals. The switch 51, Fig. 11, serves to cut in and out the apparatus, as -may be desired.
